For anybody trying to do this, I have found a resolution. To change the "Other User" text you will have to change permissions to the file and move the file into the En-US folder to replace the current one in one script.
This is what I came up with.
Step 1: Code for the credprovhost.dll.mui file replacement;
"
# Set the file path for the file to be moved$file = "$PSScriptRoot\credprovhost.dll.mui"$destination = "C:"Copy-Item $file $destination -Force$filePath = "C:\Windows\System32\en-us\credprovhost.dll.mui"$acl = Get-Acl $filePath$rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Everyone","FullControl","Allow")$acl.SetAccessRule($rule)$rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Administrators","FullControl","Allow")$acl.SetAccessRule($rule)$rule = New-Object System.Security.AccessControl.FileSystemAccessRule("SYSTEM","FullControl","Allow")$acl.SetAccessRule($rule)Set-Acl $filePath $acl$sourceFile = "C:\credprovhost.dll.mui"$destinationFile = "C:\Windows\System32\en-US\credprovhost.dll.mui"# Backup the original fileCopy-Item $destinationFile "$destinationFile.bak"# Replace the original file with the replacement fileCopy-Item $sourceFile $destinationFile -Force
"
Step 2: Package the .ps1 file (with the credprovhost.dll.mui file within the package) using "IntuneWinAppUtil.exe" Application.
Step 3: Upload to Intune
